SEQUENCE OF EVENTS RECORDER FACILITY FOR AN INDUSTRIAL PROCESS CONTROL ENVIRONMENT - A sequence of events (SOE) recorder facility in a process control network environment is described herein. The SOE recorder facility is hosted by a networked node that receives digital signal status change (event) data from a networked controller. The sequence of events recorder facility receives a configured set of digital data signals from the controller, temporarily buffers the events in chronological order according to timestamps assigned to the events by their sources (e.g., fieldbus modules). The data is thereafter copied/removed from the buffer and provided to multiple destinations including: a process database that maintains an archival copy of the received event data for rendering event reports, and an SOE client user interface for rendering event logs to printers and/or graphical user interface displays.

HANDHELD WORK APPARATUS HAVING A DRIVE MOTOR FOR DRIVING A WORK TOOL AND METHOD FOR OPERATING SAID APPARATUS - A handheld work apparatus has a drive motor for driving a tool, an operating element for operating the drive motor, a first inhibiting unit and a second inhibiting unit. Each inhibiting unit has a disable state and an enable state. The operating element is inhibited for operating the drive motor when at least one of the inhibiting units is in its disable state. The work apparatus further has a locking device which locks the first inhibiting unit in its enable state if the second inhibiting unit is in its enable state. A method for operating the work apparatus provides that the first inhibiting unit is locked in its enable state when the first inhibiting unit and the second inhibiting unit are situated in their enable states at the same time.

Process and Device for Controlling a Gearsift of an Automatic Gearbox - The present invention relates to a method for controlling an automatic transmission, which allows a gear change and, here in particular, downshifting with minimum traction interruption while the phase of reduction of the drive torque of the drive motor, the phase interruption of the frictional connection phase in the automatic transmission, and the phase of rotational speed adjustment in the transmission input shaft are designed for a suitable target rotational speed such that they overlap at least in part. In particular, with interruption of the frictional connection in the automatic transmission, the drive motor transmits a drive torque to the input shaft of the automatic transmission via the main clutch, which achieves a change in the rotational speed of the input shaft of the transmission (n_ge) in the direction of the synchronous speed of the new gear. The present invention also relates to an apparatus to carry out this method.
